Specicaton of Letters Patent.

Application led September 9, 1907. Serial No. 391,864.

4T 0 all whom it may concern: l

Be it known that I, WILLIAM B. SnarrinLn, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Automat-ic Ink- Distributers for Printing-Presses, of which the followinff is a specification.

My invention relates to improvements 1n automatic ink-distributers for printingpresses, and my objectis to obtain a more uniform distribution of ink on the rotary disks of job-presses than has heretofore been had. I attain this object by interposing a roller between the ink-fountain'and the customary form rollers of the press. This roller is carried u to the ink-fountain, receives a supply of in r therefrom, and then distributes the same uniformly upon the disk so that when the form rollers pass over the same they will be ,evenly and thinly coated. The result is that the type over which the form rollers pass is evenly coated with ink instead of b'ecoming clogged therewith as is frequently the case -Where one of the form rollers takes its supply directly from the ink-fountain, as in the latter instance it does not have time to properly distribute the ink before running over the form of type.

Referring now to the accompanying` drawings, which illustrat the invention, Figli re l represents a broken side elevation ofthe uper portion of a job-press provided. with my im rovements. Fig. 2 is a view of the same loo ring in the direction of arrow a, Fig. 2

1 designates the frame of the press, 2 thev bed thereof for receiving the form of type, 3 a pair of rocker-arms, 4, rods yieldingly-carried by the rocker-arms, 5 the form rollers Iwhich are journaled in bearings 6 carried by rods 4, 7, arotary inclined disk, 8 and Q, a ratchet-wheel and pawl, respectively, forming part of the gearing for rotating the disk, and 10, a track the rails ci which are at opposite sides of the lower portion of the disk.

All of the'above parts are old in the art and form no part of the present invention, which consists of the parts hereinafter described..

1l designates an independent ink-distributing roller adapted to pass up and down over the face ofthe disk for the purpose of supplying ink thereto and to assist in distributing the ink thereon` Said roller provided with a shaft 12 mounted in a pair of wheels 13, which pass upon the track as the roller approaches the end of its downward ward over the face movement and raises the same above the disk so that said disk may rotate without injuring the surface of the roller, which, preferably, consists of the composition from which ink-distributing rollers are usually made. The downward movement of the independent roller 11 is limited by a pair of loops 14 contacting with a pair of stops 15 at vthe undersides of the rails forming track 10. As roller 11 does not pass downward over the form of type there is no danger of it coniiicting with the grippers of the press, hence it is made larger .in diameter than the form rollers to increase its effectiveness in distributing the ink upon the disk.

' Loops 14 straddle wheels 13 and are loosely mounted upon shaft 12, so that when the latter rotates with the roller the loops will not turn therewith but will depend therefrom and thus be in position to pass under the pointed ends of the track and engage stops 15 when the roller moves downward to the position shown in Fig. 1.

Roller 1l. is carried upward to an ink-fountain 20, at each oscillation of rocker-arms 3 by a pair ot' arms 16 secured by bolts 17 to eyes 18 on bearings 6, as shown in Figs. 1 and 2. The upper ends of arms 16 have notches 19 which are carried up into engagement with shaft 12 and push the same, together with the independent roller 11, upwardly over the surface of disk 7 until said roller contacts with and receives a supply of ink from a feed-roller 2l, forming art of the inkfountain above rcferred to. hen when the rocker-arms 3 carry arms' 16 downward the latter will guide the independent roller over the face of the disk so that it may ,distribute the ink thereon, which ink is further distributed upon the disk when the independent roller and the form rollers again travel upof the disk. ,As the form rollers pass over the disk the second time they not only assist roller 11 in evenly distributing the inkv upon the face of the disk, but take up a thin coating of ink and carry the same over the face of the ty e, locked in the form (not shown) carried bylbed. 2. The above operation is repeated each time the rocker-arms 3 oscillate.

By mounting roller 11 in the manner shown and described it may be instantly removed froin the press when it is desired to wash the ink from the face of disk 7 and the roller.

By taking the ink from the fountain and tor their su p 'before it could evenly distributing it over the face of the disk with the independent roller prior to coatin the.

form rollers, it is evident the latter Wi receive a more uniform coating of ink than if permitted to pass directly to the fountain y, in which instance it is obviousnthat t e 'foremost roller would receive a thicker coating than its companions, and distribute the ink upon an excess thereof over type and. coat the same too of members traveling with the forinfrol ers the independent roller upon the ink-tountain, and means on the which carry disk to the press for checking the movement of the distributing roller before it reaches the bed.

2. The combination With a printing-press provided With lan inclined rotary disk, a bed Vand the customary are adapted to travel over the disk and the bed, of upper portioncf the disk, an independent inledistributing roller, a pair of notched arms secured to the bearings of the form rollers adapted to engage the shaft of the independent roller and carry the same uptlie disk to the ink-fountain, and means on the press 'for checking the movement of the istributing roller before it reaches the bed.

3. The combination With a printingpress provided with a bed, an inclined rotary disk, a-track near'the lower end ot the disk, and the customary form rollers adapted to travel over the disk and the bed, of anu'iik-iountain located above the upper portion ol the disk, an independent ink-distributing roller which form rollers which latterv an ink-fountain located above the.

and means carried by the independent roller which engage the track and limit the down- 'Ward movement of said independentroller. 55
